ICS bearing steel spring guide Ver 2

ICS steel spring guide with a ball bearing. Its tough metal construction makes it suitable for even the strongest springs. The ball bearing makes the rotation of the spring easier and reduces resistance leading to a smoother gun operation.

Works well with a piston head with bearings. The spring is then set freely with smooth axial rotation, which reduces the resistance during its compression to a minimum.

Suitable for guns with V2 gearbox (M4/16, G3, MP5, etc.).
